Download Specs Download Manual

The Enforcer Seco-Larm E-931-S45RRQ is a retro-reflective photoelectric beam sensor designed for access control, security, and automation applications. With a sensing range of up to 45 feet (14m), this sensor ensures reliable object detection using infrared LED technology.

Important Note: This photoeye is only compatible with gate operators manufactured prior to the 2018 EL325 safety guidelines, which require a monitored photoeyes. It will not work with newer gate openers that mandate monitored sensing devices.

Key Features

• Up to 45ft (14m) Sensing Range – Adjustable detection distance for various applications.
• Infrared LED Technology – Provides accurate object detection with minimal interference.
• Weatherproof (IP66) Enclosure – Designed for indoor and outdoor use in all environments.
• Adjustable Response Time (5-100ms) – Helps eliminate false triggers caused by weather or debris.
• SPDT Relay Output (NO/NC/COM) – Compatible with a wide range of older gate operators.
• LED Alignment Indicators – Simplifies installation and troubleshooting.
• Multi-Voltage Operation – Supports 12-250V AC/DC for flexible power options.
• Includes Reflector with Hood – Ensures optimum beam focus and performance.

Conclusion

The Enforcer Seco-Larm E-931-S45RRQ is a reliable, high-performance photoelectric beam sensor built for gate automation, security systems, and industrial applications. However, it is only compatible with gate operators made before 2018 due to EL325 guideline changes. For post-2018 gate openers requiring a monitored photoeye, a different model must be used.
